Sure thing. Just don't go crazy. If you're into OpenSource type tuning I suggest (WARNING: NO AFFILIATION other than BEING A CUSTOMER. Me suggesting folk GO to this site, and contact them in NOW WAY implicates me as a part of this BUSINESS) visiting www.camtuning.com
For the record - I STILL have a HORRIBLE exhaust leak at the junction tween the DP and the OEM exhaust.
Going to give it one-more try before taking to a muffler shop.
